Abstract
Provided is a transmitter that includes a channel selector for modifying an operating frequency of a radio-controlled toy. The transmitter has a channel selection switch that enables a user to pick a channel from a set of predefined channels. The selected channel is then transferred to the toy. For example, a microcontroller unit within the transmitter may be used to detect the selected channel. The toy is placed in contact with the transmitter and the transmitter'"'"'s microcontroller unit communicates the channel to a microcontroller unit inside the toy. The toy'"'"'s microcontroller stores the channel in a memory in the toy. The toy then tunes to the stored frequency to receive control signals from the transmitter.

16. A transmitter for a radio-controlled toy, wherein the toy includes a programming contact and at least two charging contacts, the transmitter comprising:
-
a housing;
a frequency selection circuit positioned within the housing;
a charging circuit positioned within the housing;
an interface pad proximate to a surface of the housing, wherein the interface pad provides electrical communication between the frequency selection circuit and the programming contact of the toy to transfer frequency selection information from the frequency selection circuit to the toy, and wherein the interface pad further provides electrical communication between the charging circuit and the charging contacts of the toy; and
a channel selection switch on the housing for selecting one of a plurality of predefined frequencies for the transmitter and the toy;
wherein the selected frequency is set as an operating frequency of the transmitter and toy during charging of the toy, and wherein the operating frequency is used for communications between the transmitter and toy. - View Dependent Claims (17, 18, 19, 20)
